Saving data from a loop

Goodday everyone,

I am a newbie in using matlab software and I find it difficult on storing an answer from a loop in a designated variable. I was planning to store the roots of an equation by which the constant variables of the 6th degree polynomial was imported from excel file. I was planning to store the values in columns of the "h" variable. Hope you can help me regarding this matter. The matlab code that i created is shown below.

Thank you very much!

data=xlsread('Soil Characterization.xlsx',5,'C17:K23');   
L=length(data(1,:));
x=1;
for xx=1:L+1;
  if (xx<L+1);
      a = data (1, xx);
      b = data (2, xx);
      c = data (3, xx);
      d = data (4, xx);
      e = data (5, xx);
      f = data (6, xx);
      g = data (7, xx)-10;           
      y=[a b c d e f g];
      w=roots(y);
  end
  h(x,:)=w;
  x=x+1;
end

data=xlsread('Soil Characterization.xlsx',5,'C17:K23');
L=length(data(1,:));
h=zeros(L,6)
for xx=1:L;
  y=[data(1:6,xx)' data (7, xx)-10 ];
  w=roots(y);
  h(xx,:)=w';
end

Goodevening sir, I tried using this code but an error occurs on "h(xx,:)=w';" part. I cant figure out what is wrong. hmmm.

Post the error message

[Azzi Abdelmalek]

And if possible post a sample of your data

[Ezequiel Male]

Error in ==> SolvingRoots at 11 h(:,xx)=w';

this is what matlab always tell me.

Please post the complete error message.

[Ezequiel Male]

??? Subscripted assignment dimension mismatch.

Error in ==> SolvingRoots at 11 h(:,xx)=w;

its all what matlab says. i dont know why when i look in the "h" array, all the values are zero

[Azzi Abdelmalek]

you wrote

h(:,xx)=w;

In my code it's

h(xx,:)=w;

i've done what you told me to do yet it still said the same thing. same error message
